Safety Information
- Always disconnect power before working on electrical components inside the enclosure.
- Ensure all connections are secure and properly insulated.
- Do not exceed the electrical ratings of the components installed within the box.
- If drilling holes for cable glands or mounting, ensure proper sealing to maintain the IP65 rating.
- Consult a qualified electrician for complex installations or if you are unsure about any procedure.
Installation Guide
Follow these steps for proper installation of your LeMotech electrical junction box:
- Prepare the Enclosure: If you need to route cables, carefully drill holes for cable glands in the desired locations. Ensure the hole size matches the cable gland for a tight seal. The ABS plastic is designed for easy modification.
- Install Internal Components: Mount your electrical components (e.g., terminal blocks, PCBs, relays) inside the box using the integrated mounting points. The box features brass inserts for secure screw fastening.
- Install the Gasket: Place the rubber gasket securely into the groove around the perimeter of the lid. Ensure the gasket is fully seated and forms a continuous seal. If the gasket appears too short, gently stretch it to fit the entire groove.

- Secure the Lid: Place the lid onto the base, aligning the screw holes. Insert the four metal screws and tighten them evenly to compress the gasket and create a watertight seal. Do not overtighten.
- Mount the Enclosure: Secure the entire enclosure to your desired surface using appropriate mounting hardware (not included).
Operation
The LeMotech electrical junction box functions as a protective housing for your electrical and electronic components. Once installed and sealed, it provides a secure environment against environmental factors. No specific operational steps are required for the box itself beyond ensuring it remains properly closed and sealed.

Maintenance
- Regular Inspection: Periodically check the enclosure for any signs of damage, cracks, or loose screws.
- Gasket Integrity: Ensure the rubber gasket remains flexible and free from tears or degradation. Replace if necessary to maintain the IP65 rating.
- Cleaning: Clean the exterior of the box with a damp cloth. Avoid using harsh chemicals that could damage the ABS plastic.
- Screw Tightness: Occasionally check that the lid screws are snug. Do not overtighten.
Troubleshooting
- Water or Dust Ingress: If you observe water or dust inside the enclosure, immediately disconnect power. Check the gasket for proper seating and damage. Ensure all cable glands or drilled holes are properly sealed. Retighten lid screws evenly.
- Lid Not Sealing Properly: Verify the gasket is correctly installed in its groove and is not pinched or misaligned. Ensure all four screws are tightened evenly.
- Cracks or Damage: If the enclosure develops cracks or significant damage, its protective capabilities may be compromised. Consider replacing the unit to ensure continued protection of internal components.
